As a matter of caution it sets it to the default gcc errorformat:
```
errorformat=%*[^"]"%f"%*\D%l: %m,"%f"%*\D%l: %m,%-Gg%\?make[%*\d]: *** [%f:%l:%m,%-Gg%\?make: *** [%f:%l:%m,%-G%f:%l: (Each undeclared identifier is reported only once,%-G%f:%l: for each function it appears in.),%-GIn file included from %f:%l:%c:,%-GIn file included from %f:%l:%c\,,%-GIn file included from %f:%l:%c,%-GIn file included from %f:%l,%-G%*[ ]from %f:%l:%c,%-G%*[ ]from %f:%l:,%-G%*[ ]from %f:%l\,,%-G%*[ ]from %f:%l,%f:%l:%c:%m,%f(%l):%m,%f:%l:%m,"%f"\, line %l%*\D%c%*[^ ] %m,%D%*\a[%*\d]: Entering directory %*[`']%f',%X%*\a[%*\d]: Leaving directory %*[`']%f',%D%*\a: Entering directory %*[`']%f',%X%*\a: Leaving directory %*[`']%f',%DMaking %*\a in %f,%f|%l| %m
```
so that the compiler keeps working after switching to others.
While likely only a subset is needed; such a subset has been proposed in
a commented errorformat;
checked to work for yamllint but ran out of steam for other compilers;
